Sweep your casings

I came across a "Community Shooting Range" apparently owned by the city of Valdez, Alaska.  Apparently it's free and you just drive up and start shooting.  The openness of the gun culture in Alaska is something like I've never seen before.  The other day I saw a little girl walking down the side of the road with what appeared to be a rifle.  It's a different world up here. By the way, one of the few rules posted at the Community Shooting Range is "Please sweep your casings".  Looks like some people aren't following the rules. :)
